Antivries doodt door binnen in je lichaam om te zetten in oxalaat, en spinazie levert je kant-en-klaar oxalaat.

Ethyleenglycol, het spul in de radiator van je auto, smaakt zoet. Daarom zien dierenartsen zoveel katten en honden die het van een garagevloer hebben opgelikt. Op zichzelf doet het verrassend weinig. De schade begint wanneer de lever aan de slag gaat en het stap voor stap afbreekt tot glycoliJzuur en vervolgens oxaalzuur.

Het oxaalzuur trekt calcium uit het bloed en zet het om in calciumoxalaat, een kristal. De kristallen nestelen zich in de hersenen, het hart en, het ergst van alles, de kleine buisjes van de nier, die ze verstoppen en openscheuren. Oxalaatkristallen in de urine zijn hoe een arts weet dat het antivries was.

- Dodelijke dosis: iets meer dan 1 mL per kilo lichaamsgewicht
- Voor een volwassene van 70 kg: ongeveer 70 mL
- Het klassieke tegengif: alcohol, dat het leverenzym bezet zodat het oxalaat nooit wordt gemaakt

Spinazie, rabarber, bietbladeren, amandelen en zwarte thee slaan de leverstap over. Hun oxalaat arriveert al kant-en-klaar.

In 2014 ging een 56-jarige man in Arkansas naar het ziekenhuis met misselijkheid, zwakte en overal pijn. Zijn nieren zaten verstopt en ontstoken met oxalaat. Er was geen nierziekte in zijn familie en niets mis met zijn darmen. Hij dronk ongeveer 16 koppen ijsthee per dag, wat zijn oxalaat op 3 tot 10 keer zette wat de gemiddelde Amerikaan binnenkrijgt. Zijn artsen schreven over hem in het New England Journal of Medicine, en hij ging aan dialyse, mogelijk voor de rest van zijn leven.

Zelfde kristal, hetzelfde orgaan.

Spoedeisende hulp geeft het antivriesoffer een stevige borrel om te voorkomen dat zijn lever oxalaat maakt. De saladebar serveert het aan iedereen anders voor-gemaakt en noemt het een superfood.


Geloof er niks van, Popeye wordt toch sterk van spinazie :).
 
"How have you got any energy if you haven't had breakfast?"

I've got about two months of fuel strapped round my middle. I'm just using a bit of it.

"I thought fat was hard to get at."

It is if you keep posting sugar through the letterbox every three hours. The body never has to go to the tank, so it forgets where the tank is.

"So you just don't eat at all?"

Not until I'm hungry. About one, two o'clock. Then I eat like it's about to be discontinued.

"Don't you get shaky?"

No. Shaky is what happens when you've had a bowl of cereal at seven and you're coming down off it by ten. I never went up, so there's nothing to come down from.

"What about your metabolism, though?"

It's a body, not a boiler. It doesn't go out because you missed the toast.

"It just sounds a bit disordered, if I'm honest."

You eat six times a day, you've got a biscuit drawer, there are cereal bars in your glovebox, and you panic if the eleven o'clock snack is late. Which one of us sounds like he's on a drip?

"My dietician says breakfast is the most important meal of the day."

Your dietician's quoting a cereal advert from 1917. I'm quoting a lion. The lion skipped breakfast and ate the dietician.

The supermarket chicken is 42 days old, and it's had a hard 6 weeks.

Chicken:
- 6 weeks in a shed, 19 to the square metre
- 2.5kg, legs buckling under its own breast
- Over a quarter walk badly by catching day
- Fed soy and maize, never a blade of grass
- Fat about 5x higher in omega-6
- Breast tastes of whatever you marinated it in
- Needs a sauce, a rub and a sprinkle of creatine

Mutton:
- 5 years on a hill, in all weathers
- Walked for every mouthful
- Made its own fat from grass
- Gram for gram, about 4x the iron, 5x the zinc, 10x the B12
- Fat that stays solid in the pan and crisp on the plate
- Tastes of the hill it grew on, with salt
- Needs nothing but an oven and time

Only one is on the dietician's list, and it's the one that struggles to walk.

1908: a Smithsonian doctor examines around 2,000 Native Americans still living on game and finds exactly two cases of cancer, in a population where a modern doctor would expect hundreds.

1913: a missionary doctor arrives in Gabon, examines thousands of patients a year living on fish and game, and reports he could not find a single case of cancer.

1920s: a doctor working among Labrador's Inuit on seal, fish and caribou sees no cancer, no appendicitis and no heart disease in a decade, and then watches all three arrive with the trading post.

1935: the first cancer in a Canadian Inuit population is recorded at that post, within a generation of the shop opening.

1964: a cardiologist tests 400 Masai warriors on milk, blood and meat and cannot find a single heart attack, in men eating more saturated fat than anyone in America.

1990: a Swedish doctor examines every adult on the island of Kitava and finds not one stroke, not one heart attack and not one case of diabetes among 2,300 people who have never opened a packet.

2026: half of British people born after 1960 will get cancer, and heart disease kills more people than anything else on earth.

The diseases we're told are the price of living longer were so rare in people living on the animal that doctors crossed oceans to confirm it, and came back with the same empty notebook every time.

Each of them was told it was a coincidence, and each of those populations was then given the shop.

Nobody has ever had to ship cancer to a people. A sack of flour and a drum of seed oil are lighter, and between them they do the job.

A cow and the activist trying to ban her have been emitting since 2002. Only one of them has made any progress.

2002
Daisy I: eats the field, burps the field. Carbon: 1 summer old.
Jasper, 0: driven home from hospital in a diesel Volvo. Carbon: 100 million years old.

2008
Daisy II: eats the field, burps the field. Carbon: 1 summer old.
Jasper, 6: first flight, Majorca. Carbon: 100 million years old.

2014
Daisy III: eats the field, burps the field. Carbon: 1 summer old.
Jasper, 12: half-term in Dubai. Carbon: 100 million years old.

2020
Daisy IV: eats the field, burps the field. Carbon: 1 summer old.
Jasper, 18: glues himself to a road in a fleece made of oil. Carbon: 100 million years old.

2026
Daisy V: eats the field, burps the field. Carbon: 1 summer old.
Jasper, 24: flies to Turkey to tell the UN about Daisy. Carbon: 100 million years old.

Every burp in that family tree was grass the summer before. The methane breaks down in about 12 years, the grass takes it back in, and the next Daisy eats it. Five cows, one field, the same carbon going round and round, and not a gram added to the sky.

Jasper's carbon spent 100 million years underground bothering nobody. He dug it up and set fire to it, and a good chunk will still be up there when Daisy the 170th is eating the same field.

Daisy hasn't changed a thing in 24 years. According to Jasper, that's the problem.

Your stomach runs at a pH of about 1.5, which is the acidity of a scavenger, and it does that on purpose.

That acid kills most of the bacteria that arrive with your dinner.

That acid prises B12 off the protein it comes in, so the body can collect it.

That acid releases the iron, calcium, zinc and magnesium locked inside your food.

That acid switches on the enzyme that breaks protein into the amino acids you're built from.

That acid is the signal that tells the rest of the gut the meal has started.

A lion makes it. A vulture makes it. A newborn baby makes it by the first week.

Then we declared war on it.

England now writes well over 60 million prescriptions a year for pills that switch it off, mostly for heartburn from a diet of bread, pastry and seed oil.

Around 15 million Americans are on the same pill.

Low B12 is now so common in long-term users that the regulators warn about it.

Hip fractures rise in people who take it for years, because calcium stops being absorbed.

Gut infections rise, because nothing is killing what comes in.

A fifth of users were never told to stop, so the war on stomach acid has become a lifetime subscription.

The stomach spent two million years learning to make it, and we switched it off for a sandwich.

In January 1961 Time put Ancel Keys on its cover, took its readers to dinner at his house, and let him tell America to cut its fat by almost two thirds before his own great study had produced a single result.

The dinner was the sales pitch. Brahms on the record player, candles on the table, a meal that could run two hours, martinis or negronis to start. Veal scallopine in Marsala with fresh green beans. A thousand calories, the magazine reported, and only 20% of them from fat.

That was how Keys wanted the country to eat. Fat down from about 40% of America's calories to 15%, and saturated fat from 17% to 4%. "Eat less fat meat, fewer eggs and dairy products," he said, and more fish, chicken, Canadian bacon, and Italian and Chinese food.

"People should know the facts," he told Time. "Then if they want to eat themselves to death, let them."

The facts that winter were thin. The study of seven countries that was meant to prove him right had only started its surveys in 1958 and had years left to run. What he had was a chart of six countries, picked from the 22 he could have used, and a seat on the American Heart Association committee that had just turned his idea into its first official advice on fat.

The cover did the rest. A physiologist's hunch went into American homes with a playlist and a cocktail menu attached, and it went in as settled science.

In 1965 his own equation for predicting blood cholesterol gained a term for the cholesterol in food. In 1968 the Heart Association told Americans to eat no more than three whole eggs a week. In 1984 Time ran another cover, two fried eggs and a rasher of bacon arranged into a frowning face. For decades American dietary advice held the country to 300mg of cholesterol a day, less than two eggs, until the government's advisers recommended dropping the limit in 2015.

In 1997, aged 93, Keys gave an interview to a food magazine.

"There's no connection whatsoever between cholesterol in food and cholesterol in blood," he said. "And we've known that all along. Cholesterol in the diet doesn't matter at all unless you happen to be a chicken or a rabbit."

We've known that all along.

Thirty-six years earlier he had told Time to tell America to eat fewer eggs, by candlelight, with a negroni in reach.
